Thread: IAT 2 temp input signal from LSJ 2.5 BAR MAP sensor (L61 SC Build)

    IAT 2 temp input signal from LSJ 2.5 BAR MAP sensor (L61 SC Build)

    Hi - added an M62 Supercharger to a 2.2 L61 in a cobalt. Stock the L61 does not have IAT2 temp input to the ECM, only IAT, and the stock MAP does not have a temp sensor (IAT2).

    If i add a LSJ 2.5 bar MAP sensor that includes a 4th wire for the IAT2 temps can i use this wire signal as an input to the MPV2 pro link (currently have WB connected) and read IAT2 temps? If so, how would i calibrate the voltage to temp?

    And/or... is there a way to connect this IAT2 signal wire from the MAP to an external gauge to display the temp? (assuming would have to be a gauge that could be calibrated)

    Thanks
